On Friday Apple's iPhone 11 went on sale in South Korea. Some 130,000 units of Apple Inc.'s new iPhone models are believed to have been sold on the first day of sales in South Korea, industry insiders said Saturday.

Apple released its iPhone 11, iPhone 11 Pro and iPhone 11 Pro Max in South Korea on Friday, targeting consumers looking for premium phones available in 4G LTE models.

The estimated figure is 30 percent more than the previous iPhone models -- the iPhone XS, Max and XR -- launched November 2018, according to industry sources.

While sales were lower than local favorite Samsung when the Galaxy Note 10 went on sale in August, the iPhone's strong performance is still considered a big win for Apple that didn't offer a 5G version.

Industry insiders said local consumers were apparently moved by positive responses from the US and Japan, where iPhone 11s were launched one month earlier than South Korea, while some have opted for 4G models over concerns about 5G service quality.

Apple's iPhone 11 launched on the very same day that trial proceedings for Samsung Electronics’ de facto leader Lee Jae-yong and other top executives restarted.

Korea's Supreme Court in August overturned an appeals court’s decision to hand the Samsung heir a suspended jail term. The next hearings are scheduled for Nov. 22 and Dec. 6.
